1. The propeller of a boat at dock in the ocean will rise and fall with the waves. On a particularly wavy night, the propeller leaves its resting position and reaches a height of 2.5 m on the peaks of the waves and -2.5 m in the troughs. The time between the peak and the trough is approximately 2 seconds. Determine the equation of a sinusoidal function that would model this situation assuming that at t = 0, the propeller is at its resting position and headed towards the peak of the next wave.
